So I have a two-dimensional array of Int

var boardArray = Array(repeating: Array(repeating: 0, count: 8), count: 8)
boardArray[4][4] = 1

Now I would like to get a two-dimensional array of String. 0 -> "-" 1 -> "*"

let z = boardArray.map{a in a.map{v in 
       if v == 0 {
            return "-"
        }
        else {
            return "*"
        }

        } }

And so I have a compile-time error 'Ambiguous reference to member 'map''. What should I do?

`let z: [[String]] = boardArray.map { array in array.map { $0 == 0 ? "-" : "*" } }` – Leo Dabus Sep 04 '18 at 12:40
